To ensure the perfect fit, please measure around your dog's neck and consult the collar size chart below. When in doubt, size up!

 

Measuring Tips:

Measure your dogs neck where the collar will naturally sit (A). 

Use a soft tape measure, pulling the tape snug but not tight (if you don't have a tape measure, use a piece of string and then measure the string with a ruler).

Allowing two fingers to snugly fit between the tape and your dog's neck.

You got it!..
